Let me start with, I have absolutely no idea what I'm doing!
I received a previously used\configured PowerConnect 3548p that I'll be setting up in a home test lab. I have my console cable attached, launched PuTTY, fired it up, and get output. It wants a username\password that I just don't have.
I interrupted normal boot to get into the Startup Menu. Erased Flash File, then entered a name. Below is the output on the startup menu I received.
I hoped this would set the password back to a default. I have tried admin:password, admin:<nothing>, root:calvin.
